...Top Five Most Stolen Cars Math 222 7 October 2013 There is a probability that cars on the top ten stolen car list would be stolen over other cars that thieves steel in the United States annually. There is a car stolen every 26.4 seconds in the United States today. According the National Insurance Research institute that is 715,373 in the year 2012. This paper is a statistical look at what are the five most stolen in the United States (US).

I have also done my own research to show how many cars of the top five stolen cars are in the neighborhood I live in to support the data in this paper. I will also compare it to all the other cars that are not on the list so you can see how frequently cars on the top five stolen car list appear around you. When compiling the data the realization that none of my sources raked the top five stolen cars in the same order. This is because the research materials were written in many different states. Researching further if I had used all the data together the data would give outliers in the statistical analysis. So I chose to use the data from the National Insurance Research Institute for this paper. Looking at the numbers, the number one stolen car in the US is the Honda Accord 58,596. Number two on the list the Honda Civic with 47,037 cars stolen. Statics show that it is in the number two spot with a difference of 11,559 cars...

Q1 * Risk-weightings at the "standardised banks" such as Kiwibank, TSB, SBS and the Co-operative Bank start from 35 per cent, but a Reserve Bank spokesman told North & South that risk weights for the Big Four's housing loans "are generally between 26 and 31 per cent".
